Adds an optimization for checking whether a looper is stuck,
with a new Looper method to see if its thread is currently
idle. This will allow us to put a large number of loopers
in the monitor efficiently, since we generally won't have to
do a context switch on each of them (since most looper threads
spend most of their time idle waiting for work).
Also change things so the system process's main thread
is actually running on the main thread. Because Jeff
asked for this, and who am I to argue? :)

Basic implementation of an undo manager. Supports
multi-level undo/redo, building on the top undo state
as edits occur, managing multiple distinct entities in
the undo state (such as embedded objects in a document),
and saving/restoring the full undo state. Still some
work remaining on correctly dealing with dependencies
between undo states that hold multiple owners.
Also do a simple implementation of undo state in TextView
to see how things actually work. The implementation here
is very primitive: it needs a lot more work to correctly
identify when to merge undo ops, is not trying to do
anything smart with style spans, etc.

Media buttons: note when an application tries to take ownership
of the media buttons.
Audio focus: note when an application tries to take audio focus.
Volume levels: note changes to the volume level of the various
streams.
Maybe we should also have some ops for muting streams, soloing
streams, etc?

Fixed b/8834502. Wake lock might not be released when the callback is null.
NPE is thrown when the callback is null in some cases too.

IActivityController has a new callback which the Watchdog calls
when it detects that the system process is hung. This may be
use full monkey. All hail the monkey!
Also add a new private feature to Binder to be able to turn off
all incoming dump() calls to a process. The watchdog uses this
when it reports it is hung, so that if someone, say, wants to
collect a bug report at this point they won't get stuck waiting
for things that are all busted.

The counter can be enabled by setting the system property called
debug.hwui.overdraw to the string "count". If the string is set
to "show", overdraw will be highlighted on screen instead of
printing out a simple counter.

1. The scheduling was relying on receiving battery level broadcasts
which however are not sent if the device is asleep. The maintenance
window was not bound and we could miss a frame if the user did
not interact the device longer than the min time between two
maintenance windows.
2. Hide the idle maintenance intents since this will be rewritten
to user services.
